plugin-hook

@myadmin-plugins

Implements the MyAdmin plugin hook registration pattern for `src/Plugin.php`. Generates `getHooks()` returning event-to-handler map, `getRequirements()` with `add_page_requirement`, `getAddon()` with `AddonHandler`, and `getSettings()` with `add_text_setting`. Use when user says 'add a hook', 'register event', 'new plugin method', or modifies `Plugin::getHooks()`. Do NOT use for modifying existing hook handlers (doEnable/doDisable logic) or for non-Plugin.php files.
